2003 bounder ford v10 no start

What a dumb place to mount an extremely crucial relay. Paul perhaps they thought the splash up from the road would cool it!
Anyway, "Thanks" to all for your responses.
We are now about 500 miles into our trip to Glacier National Park.

FLANZ & FC, you both nailed it, Starter solenoid on radiator mount, cleaned connections thoroughly, started right up.

I thank all for your interest and comments.

Just another bit of advice going forward with this solenoid. When I was fixing mine, I noticed that there was a lot of heat generated at and on this part, most likely due to the fact that it's mount on the radiator bracket. I decided to carry a spare based on this. It turn out to be a VERY valuable part because it eventually died. I think I paid $25 for the part. Just something you may want to consider depending on how long you plan to keep the MH. Worst case, find out the part number and keep this handy.

Glad I could help. It seems like such a simple thing to do but it works. LOL
The Tech that was sent to our site found the problem in 45 minutes and charged me an hour, while the road service paid for his trip to and back.( $150)
It was a Friday afternoon and we expected to be spending a weekend at a local Ford Dealer. The TECH was excellent.

You said the horn makes a very slight noise, that still sounds like a compromised wire or connection somewhere. PCM sounds way off but sometimes you never know.

Bryan, I am also suspicious of the PCM diagnosis.
fischer, the steps do work. Now I'm wondering about the integrity of the ignition relay itself.

are your steps working ? if your disconnect sw. is connecting your steps should work.
your horn goes from the disconnect sw thru the ignition relay to f10 in the bcc box then to the horn.

The headlights do not go through the PCM. I would be suspicious of that diagnosis.

I've seen this from corrosion inside the battery cable. Externally it looked fine, and only started digging deeper (literally, with a knife) when I didn't have continuity using my multi-meter.
